I appreciate it, buddy. Want to build a big back? Barbell rows were key for me. I usually start with about 3 sets to warm up my back and biceps, then I go for another 4 working sets, aiming for 9 to 10 reps on my heavier sets, hitting around 405 for about 8 reps. After that, I reduce the weight while increasing the reps. Then I hit the rowing machine, trying to get 8 to 10 reps at my heaviest, before working my way back down again, squeezing the muscles hard. I follow that with single machine rows using the same approach, then I finish with lat pull-downs, starting heavy and reducing weight while adding more reps. Finally, I wrap up with pullovers, doing about 6 sets until I can't squeeze my back anymore. If you want a big back, barbell rows are the way to go.
